For most of architectures in U-Boot, virtual address is straight mapped to physical address. So, it makes sense to have generic defines of ioremap and friends in <linux/io.h>.
All of them are just empty and will disappear at compile time, but they will be helpful to implement drivers which are counterparts of Linux ones.
I notice MIPS already has its own implementation, so I surrounded the defines with #ifndef CONFIG_MIPS ... #endif. I guess Sandbox will need its own implementation as well.
how about introducing a Kconfig symbol like CONFIG_HAVE_ARCH_IOREMAP which MIPS and Sandbox can select?
Good idea!
I will do so in v2.
